Clarify documentation in the use of struct drm_driver.last_close and struct drm_mode_config_funcs.output_poll_changed. Those callbacks should not be said for fbdev implementations on top of struct drm_client_funcs. Signed-off-by:

Remove include statements for <drm/drm_fb_helper.h> where it is not required (i.e., most of them). In a few places include other header files that are required by the source code. v3: * fix amdgpu include statements * fix rockchip include statements Signed-off-by:

Move the generic fbdev implementation into its own source and header file. Adapt drivers. No functional changes, but some of the internal helpers have been renamed to fit into the drm_fbdev_ naming scheme. v3: * rename drm_fbdev.{c,h} to drm_fbdev_generic.{c,h} * rebase onto vmwgfx changes * rebase onto xlnx changes * fix include statements in amdgpu Signed-off-by: -

Uncouple the parameter drm_leak_fbdev_smem from the implementation by setting a flag in struct drm_fb_helper. This will help to move the generic fbdev emulation into its own source file, while keeping the parameter in drm_fb_helper.c. No functional changes. Signed-off-by:

Initialize the generic fbdev emulation even if it has been disabled on the kernel command line. The hotplug and mode initialization will fail accordingly. The kernel parameter can still be changed at runtime and the emulation will initialize after hotplugging the connector. Signed-off-by:

Pull the test for fb_dirty into the caller to avoid extra work if no callback has been set. In this case no damage handling is required and no damage area needs to be computed. Print a warning if the damage worker runs without getting an fb_dirty callback. Signed-off-by:

Implement the fbdev's read/write helpers with the same functions. Use the generic fbdev's code as template. Convert all drivers. DRM's fb helpers must implement regular I/O functionality in struct fb_ops and possibly perform a damage update. Handle all this in the same functions and convert drivers. The functionality has been used as part of the generic fbdev code for some time. The drivers don't set struct drm_fb_helper.fb_dirty, so they will not be affected by damage handling. For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and drm_fb_helper_cfb_write(). Several drivers require these. Until now tegra used I/O read and write, although the memory buffer appears to be in system memory. So use _sys_ helpers now. v3: * fix docs (Javier) v2: * rebase onto vmwgfx changes Signed-off-by:

Call struct fb_ops.fb_sync in drm_fbdev_{read,write}() to mimic the behavior of fbdev. Fbdev implementations of fb_read and fb_write in struct fb_ops invoke fb_sync to synchronize with outstanding operations before I/O. Doing the same in DRM implementations will allow us to use them throughout DRM drivers. Signed-off-by: -

The fbdev helpers implement a damage worker that forwards fbdev updates to the DRM driver. The worker's update logic depends on the generic fbdev emulation. Separate the two via function pointer. The generic fbdev emulation sets struct drm_fb_helper_funcs.fb_dirty, a new callback that hides the update logic from the damage worker. It's not possible to use the generic logic with other fbdev emulation, because it contains additional code for the shadow buffering that the generic emulation employs. DRM drivers with internal fbdev emulation can set fb_dirty to their own implementation if they require damage handling; although no such drivers currently exist. Signed-off-by:

Rename struct drm_fb_helper.fbdev to info. The current name is misleading as it overlaps with generic fbdev naming conventions. Adapt to the usual naming in fbdev drivers by calling the field 'info'. No functional changes. Signed-off-by:

Properties of 32-bit integers are returned from the OF device tree as type __be32. Convert PCI vendor and device IDs from __be32 to host endianness before comparing them to constants. All relevant machines are old, big-endian Macintosh systems; hence the bug never happened in practice.

A problem about modprobe ingenic-drm failed is triggered with the following log given: [ 303.561088] Error: Driver 'ingenic-ipu' is already registered, aborting... modprobe: ERROR: could not insert 'ingenic_drm': Device or resource busy The reason is that ingenic_drm_init() returns platform_driver_register() directly without checking its return value, if platform_driver_register() failed, it returns without unregistering ingenic_ipu_driver_ptr, resulting the ingenic-drm can never be installed later. A simple call graph is shown as below: ingenic_drm_init() platform_driver_register() # ingenic_ipu_driver_ptr are registered platform_driver_register() driver_register() bus_add_driver() priv = kzalloc(...) # OOM happened # return without unregister ingenic_ipu_driver_ptr Fixing this problem by checking the return value of platform_driver_register() and do platform_unregister_drivers() if error happened.
